ELMER T. WILLHQITE, oF woonR UFF, MIssoU-nn SCREEN-DOOR CONSTRUCTiON.

' Application filed December 15,1914. Serial No. 877,353;

and State of Missouri, have invented new and useful Improvements in Screen-Door Construction, of whichthe following 15 a specification.

This invention relates to improvements 1n screen door construction and has particular application to a metal door. l

' In carrying out the present invent on, it is my purpose to provide a screen door wherein the frame will be composed of hollow metal tubing and whereinfthe wire screen may be readily removed from the frame" and replaced when necessary.

It is also my purpose to improve and simplify the general construction of screen doors and to provide a door which will be comparatively light in weight and strong and durable in 'construction.

(Vith the above and other objects in view,

the invention consists in the construction,

combination and arrangement of parts here inafter set forth in and falling within the scope of the claims. v r r In the accompanying drawing; Figure 1 is a view in front elevation of a screen door constructed in accordance with the present invention. Fig. 2 i? '1 sectional view on the line 2-2 of Fig. 1. Fig. 3 is a fragmentary side elevation of a portion of the door showing the parts on an enlarged scale. Fig. 4 is a fragmentary side elevation of a modified form of door. Fig. 5 is an enlarged longitudinal sectional view on the line 55 of Fig. 4. Fig. 6 is a cross sectional view through one of the bars of the door.

Referring now to the drawing in detail, 1 designates a substantially rectangular frame comprising vertical side bars 2, 2 and horizontal top and bottom bars 3, 3 respectively connecting the side bars 2, 2 at the ends of the latter and coacting therewith to form the rectangular frame. The side and end bars of the frame are preferably formed ofhollow metal tubing and the meeting ends of the various bars are mitered and securely fastened to one another.

In the present instance, each section of tubing is substantially rectangular in cross section and the bars upon one side of the frame at the inner edges thereof are rabbeted as at 4: to form a continuous groove extending around the entire frame.

' Specification of Letters Patent.

ratentanov s, 1915.

5- designates the wire screen having the side and end edges thereof seated within the 1 rabbeted portions of therespective'bars, and disposed upon the sideand end edges'of the screen within the rabbeted portions of the bars are clamping strips 6 formed with apertures alining with threaded openings in the inner walls of the rabbeted'portion'to receive fastening screws 7 whereby the clamping strips will be forced into engage- .ment with the marginal edges of the screen and the latter effectively clamped between such strips'and the inner walls of the rabbeted portions 4. V V In the present instance, a vertical reinforcing bar 8 is disposed approximately 'cen tra-lly of the frame 1 and has the ends there of secured to the top and bottom bars .3, 3

respectively of'the frame. This reinforcing bar ispreferably of a thickness equalitothe inner edges of the top and bottom bars and fits within seats 9 out in such edges, suit-able means being provided to effect a rigid con nection between the reinforcing bar and the" .end bars.

Y A clamping strip 10 is placed in engage- I ment with the surface of'the screen 5 opposite from the reinforcing bar 8 and such strip is formed with apertures alining with threaded openings in the reinforcing bar to receive securing screws 11 whereby the strip 10 will be clamped into engagement with the adjacent portion of the screen. 12 designates atransversely disposed brace bar or reinforcing bar disposed at a point slightly below the horizontal center line of the door and formed oftwo sections 13, 13 disposed at opposite sides of the vertical reinforcing bar 8 and having the inner ends thereof suitably secured to the adjacent edges of the vertical reinforcing bar and the outer extremities disposed within seats formed in the inner edges of the side bars and fastened within such seats. The trans verse brace bar 12 is preferably of a thickness equal to that of the inner edges of the longitudinal bars 1 and vdisposed upon the side of the screen 5 opposite from the transverse brace bar 12 is a securing strip 14: formed ofsections corresponding to the sections 13 of the brace bar, such sections having apertures formed therein alining with threaded openings in the brace bars to receive securing'screws 15 whereby the secur-' In the modified form of the invention illustrated in Figs. 4 and 5, I have shown the end bars 3, 3 and the transverse reinforc ing bar 12 as formed of telescopic sections 16, 17, the former being adapted to telescope Within the latter. By means of this construction, the Width of the door may be varied in accordance With the similar dimension of the door opening. Any suitable aeans may be employed for holding the telescopic sections 16, 17 in adjusted position. Inthe present instance, the section 17 carries a set screw 18 designed to bind against the adjacent end portion of the section 16 to hold the parts rigidly connected.

.I claim:

In screen door construction, a substantially rectangular frame comprising vertical side bars and horizontal end bars, each formed of hollow metal tubing, said bars at one side of the frame having the inner edges thereof rabbeted to form a continuous groove around the frame, a screen having the marginal edges thereof seated Within the groove, a vertical reinforcing-bar disposed approximately centrally of said frame and having the extremities thereof secured to said end bars and disposed upon one side of said screen and formed of hollow metal tubing,

a securing strip engaging the screen at the g opposite side of said reinforcing bar, means clamping said strip against the screen, a horizontal reinforcing bar composed of tubular metal sections disposed at opposite sides of said vertical reinforcing bar and 3;;

havin the inner ends thereof connected b With the respective sides of the vertical reinforcing bar and the outer extremities secured to the inner edges of said vertical side bars, said last-named reinforcing bar Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,
